Datum Key (N/A for 900, Lathe Mode)
The Datum Key allows you to enter a datum table (maximum 99 datum points). A datum
is a point or reference location, from which you can machine a part. Datum points allow
you to machine similar programs on different parts. After you machine a group of parts,
you can place a new group on the machine and machine the same programs on the new
parts.
NOTE: Before you enter a datum table, establish a machine home position using
Absolute Zero Set – F 01 or activate EverTrack
TM
Mode – F 02.
